Upstream PR #1 landed daemon-side synthesis of H.264 SPS/PPS NAL units from the V4L2 stateless control structs. This bumps the package pin so both the userspace daemon and the kernel module pick up the change in lockstep (wire protocol grew a new DAEDALUS_REQ_FLAG_H264_META bit + struct daedalus_h264_meta — kernel and daemon MUST match). Effect on Pi 5 / CM5 hosts (higgs): ffmpeg -hwaccel vaapi against H.264 sources will actually decode through the daedalus daemon instead of failing with "non-existing PPS 0 referenced". Both arch + debian packages: pkgver 0.1.0.r20.3dd0eb0 (count from git rev-list), pkgrel reset to 1 (new upstream pin). VP9 / AV1 paths unchanged.

# daedalus-v4l2 — userspace daemon + V4L2 m2m test tools.
|
||
#
|
||
# Pair to daedalus-v4l2-dkms (kernel module). Together they expose
|
||
# /dev/videoNN + /dev/mediaNN as a V4L2 stateless decoder shim on Pi 5 /
|
||
# CM5, decoding VP9 / AV1 / H.264 via dlopen'd FFmpeg in a single-
|
||
# threaded daemon and shipping decoded NV12 / P010 back through dmabuf.
|
||
# Consumed end-to-end by libva-v4l2-request-fourier (>= 1.0.0.r376) so
|
||
# `ffmpeg -hwaccel vaapi` against vp9_small.ivf produces byte-exact NV12.
